Specification of Letters Patent.

Patented Nov. 9, 1920.

Application filed March 9, 19178. Serial No. 221,419.

T0 all whom 'it may concer/n.:

Be it known that I, Ennns'r W. PAULsoN, a citizen of the United States,and a resident of Oto, in the county of Woodbury and State of iowa, haveinvented new and useful improvements in Flows, of which the following isa specification.

The present invention relates to plows. The invention aims primarily toprovide a plow embodying certain novel features of constructionparticularly adapting the deice for use on side hills.

Another object of the invention is the production of a plow embodyingcertain novel features of construction adapted more vparticularly for acultivator, and which operate to neutralize the tendency of the machineto creep on a side hill.

A further advantage of the invention resides in the fact that themachine may be instantly shifted laterally in either direction to followcrooked rows.

Furthermore, the invention contemplates an improved cultivator,inexpensive and simple in construction, yet thoroughly efficient inoperation.

qWith these and other objects in view the invention, consisting in theconstruction, combination and novel arrangement l of parts, will hefully understood from the following description, reference being had tothe accompanying drawings, which form a part of this application and inwhich like characters of reference indicate corresponding partsthroughout the several views, of which- Figure 1 is a plan of acultivator constructed in accordance with the invention; Fig. 2 is avertical section of the same taken on the line 2-2 of Fig. 1; Fig. 3 isa fragmentary rear elevation of the same; Fig. 4 is an enlargedperspective view of the controlling mechanism and of the partsassociated therewith; and Fig. 5 is a perspective view of one of theaxle bearings and asson ciated parts.

Although l have illustrated and hereinafter describe the preferredembodiment of the invention, l would not be understood as being limitedto the specific structure chosen for illustration, for variousalterations and modiiications may be made in the details of constructionand arrangement of parts without departing from the spirit and scope ot'the invention as defined in the appended claims. i Y

.Referring now to the illustrations, the dcvice consists of a mainframe, including preferably an arched axle comprisedy of parallelchannel irons, 6 the arms of which c eclinc outwardly as at E?, and afront cross member, 8, preferably T-shaped in cross section andconnected with the axle bybars, 9. Upon the bars 9 are mounted segmentalplates 10, upon which are pivoted draft tongues, 11. At the ends of theaxle are upright shafts 12, rotatably mounted in bean ings mounted tooscillate between the axle arms these bearings preferablyl consist ofcollars, 13, which freely encircle the shafts, 12, and are providedrwithpintles, 14E, jour` naled in openings in the arms of the axle. Saidbearings rest on spindles, 15, extending laterally from the shafts, 12,and on which the travel wheels, 16, rotate. Between the axle members, 6,is positioned a shaft, 17 slidable longitudinally in bearings, 18,carried by the axle members. The ends of the shaft, 17, are providedwith eyes,19, which freely encircle the upper ends of the shafts, 12.The shafts, 12, are provided with crank arms, 20, connected by pitmen,21, with arms, 22, mounted on the rear axle member. y.

By virtue of the structure now disclosed it is evident that longitudinalmovement of the shaft, 17, will direct the wheels at an angle to thedirection of travel, and also tilt them vertically, as shown in dottedlines in Figs. 1 and 3. The device illustrated is a two row cultivatorand is provided with four gangs of plows, each consisting of a pair ofplow beams, 23, carrying at their rear ends the shovels or plows proper,24., and the forward ends of the beams are pivoted on the lower ends ofsupporting rods, 25, which pivotally depend from bearings,`26, mountedto slide longitudinally on the cross member, 8. In the `presentembodiment these bearings, 26, consist of elongated blocks which slideadjacent the lower edge of said erom member and are provided withoverturned flanges, 27, which engage the upper sides of the flanges ofthe cross member. The gangs are connected in pairs whereby lateralmovement of one gang imparts corresponding movement to the companionpair. For this purpose the bearings, 26, are provided with forwardlyextending flanges, 28, the said flange of each block beingy detachablyinterconnected with the flange of the adjacent companion bearing by abar. 2.9, bolted or otherwise secured .to the fiance, as'at 30 Theflanges are provided w'th a plurality of openings,.31, to receive thebolts 30, whereby the distances between the gangs may be altered tocorrespond with the spaces between the corn rows.`

achgangf is Vconnected with its mate by means of an intermediate yoke,32, the arms of which are mounted in bearings, 33,

mounted on the beams, and the web of which is formed with a knuckle, 34,whereby the yoke'may be spread or contracted.V @n the shaft, 17, arepivoted bars, 35, which decline forwardly and have their lower endspivoted, as at 36, to theV beams,whereby the bars, 35 and 25, c o-act astheV machine moves forwardly to depress the shovels, from which it isobvious that the greater the resistance of the earth on the shovels thegreater will be the downward pressure. This feature is not a part of thepresent invention but forms the subject-matter of my co-pendingapplication, Serial No. 221,418, filed Mar. 9, 1918.

Aends of the draft Y gageable with Y Vmay be Vformed integrally withthebearing,

rl`he machine is provided with a. drivers seat, 37, suitably supportedby the main frame.V Y

The controlling; 'mechanism consists of a shaft, 38, journaled inbearings, 39 and 40, mounted, respectively,

ber` and Vfront' cross member. 0n the said `shaft is mounted. a crankarm, 41, connected by fa pitman with an arm, 43, mounted on the shaft,17. Adjacent to itsfront end the shaft, 38, Vcarries a crankfarm, 44,connectedV by pitmen, 45, with the adjacent bearings, 26. The shaft, 38,also-carries a crank arm, 46, connected by pitm'en, 47, withthe reartongues. The shaft, 38, extends adistance rearwardly from the aXle andis crank arms, 48, which form handle bars positioned onopposite sidesofthe drivers seat.

It is now evident that by turning` the handle bars at an angle as shownin Fig. 3, the shaft, 38, will be operated to shift the tongues at anangle to themain frame `and the'main frame will be shifted laterally bythe movement ofthe shaft, 17, since the travel wheelstilt on'their lowerperipheries. Obviously the shaft, 17, moves relatively farther than themainY framewhich causes the tiltingmovement and causes one side of theframe to raise and the other to lower sition by means of a detentcontrolled by the driver f and` engan'eable with a quadrant mounted onAthe main frame. In the .present embodiment, therefore, I provide a pawlVin theshape of a bell crank,Y 49, 'fulcrumed as 'at 5 0, betw' enupri', rhts,A 51, secured to the shaft. 38; @ne arm of the bell crankisfena toothed quadrant, 52, which i ing, 54,

onthe rear aXlemem-V provided withoppositely disposedv whereby theshafts ma 39; and the depending arm is pivoted to the forward end of arod, 53, slidable in a bearmountedon the rod, 38.V The rear `end of therod, 53, is provided with a cross head, 55,' between which and thebearing, 54,

` is inter-posed a compression spring, 56, which serves to hold the pawlin yieldable ,engage- Y ment with the quadrant. '0n the laterallydisposed portions of the handle bars, 48, are fulerumedlevers, 57, theadjacent ends of which engage the headof the rod, 55, and the remoteends of which are connected by links, 53, with grips, 59, on the krearof the handle bars. It is now clear that from either handle bar theoperator can instantly control the detent. A

l also provide improved means by which the driver canmove .the pairs ofgangs toward or from each other. This means consistsof short uprightshafts, 60, journaled in bearings, 61, mounted on the beams adjacentthe. drivers seat, the said shafts being provided with crank arms, 62,interconnected by a rod, 63. :The upper ends of the said shafts areprovided with cross members, 64, suitably formed for engagement by thedrivers feet.` By forcing the adjacent ends of cross members, 64,forwardly the pai-rs of gangs will accordingly -beforced ear h towardthe other, while forward vmovement of the remote ends of the crossmembers` 64, will foce theV pairs of 'gangs eachf toward the ot er.

Having thus described my invention, what l claim as new,and desire tosecure by Letters Patent of the United States, is,-.-
